Product Overview
TPS3700 is a Texas Instruments Power_Management Power_IC configured as a window voltage detector. It monitors two input thresholds using INA+ and INB- comparator inputs referenced to an internal 400 mV comparator reference. External resistor dividers set adjustable thresholds down to 400 mV, while the device operates from a recommended 1.8 to 18 V supply range.
The output stage uses open-drain OUTA and OUTB pins rated for output voltages up to 18 V. OUTA is driven low when INA+ drops below VIT+ - VHYS and returns high when INA+ rises above VIT+. OUTB is driven low when INB- exceeds VIT+ and returns high when INB- drops below VIT+ - VHYS.
Package options include SOT-6 at 2.90 mm x 1.60 mm and WSON-6 at 1.50 mm x 1.50 mm. The datasheet recommends a 0.1 uF ceramic bypass capacitor placed close to the VDD pin. Specified operation covers -40 to 125 °C junction temperature, supporting voltage monitoring, undervoltage detection, and overvoltage detection applications.
